Currently, V4L uses a scancode table whose index is the scancode and
the value is the keycode. While this works, it has some drawbacks:
1) It requires that the scancode to be at the range 00-7f;
2) keycodes should be masked on 7 bits in order for it to work;
3) due to the 7 bits approach, sometimes it is not possible to replace
the default keyboard to another one with a different encoding rule;
4) it is different than what is done with dvb-usb approach;
5) it requires a typedef for it to work. This is not a recommended
Linux CodingStyle.
This patch is part of a larger series of IR changes. It basically
replaces the IR_KEYTAB_TYPE tables by a structured table:
struct ir_scancode {
u16 scancode;
u32 keycode;
};
This is very close to what dvb does. So, a further integration with DVB
code will be easy.
While we've changed the tables, for now, the IR keycode handling is still
based on the old approach.
The only notable effect is the redution of about 35% of the ir-common
module size:
text data bss dec hex filename
6721 29208 4 35933 8c5d old/ir-common.ko
5756 18040 4 23800 5cf8 new/ir-common.ko
In thesis, we could be using above u8 for scancode, reducing even more the size
of the module, but defining it as u16 is more convenient, since, on dvb, each
scancode has up to 16 bits, and we currently have a few troubles with rc5, as their
scancodes are defined with more than 8 bits.
This patch itself shouldn't be doing any functional changes.

* Remove smp_lock.h from files which don't need it (including some headers!)
* Add smp_lock.h to files which do need it
* Make smp_lock.h include conditional in hardirq.h
It's needed only for one kernel_locked() usage which is under CONFIG_PREEMPT
This will make hardirq.h inclusion cheaper for every PREEMPT=n config
(which includes allmodconfig/allyesconfig, BTW)

There's no point in this, since the user can use the BUILTIN_FIRMWARE

Separate tuning table for DVB-C solves tuning problem at 388MHz
TechnoTrend C-1501 DVB-C card does not lock on 388MHz. I assume that
existing frequency table is valid for DVB-T.
This is suggested by the name of the table: tda827xa_dvbt.
Added a table for DVB-C with the name tda827xa_dvbc.
Added runtime selection of the DVB-C table when the tuner is type
FE_QAM.
This should leave the behaviour of this driver with with DVB_T tuners
unchanged. This modification is in file tda827x.c
The tda827x.c gives the following warning message when debug=1:
tda827x: tda827x_config not defined, cannot set LNA gain!
Solved this by adding a tda827x_config struct in budget-ci.c.

There are several Kconfig items using CUSTOMIZE. Yet, most use the English
writing CUSTOMISE. This generates lots of trouble, because people sometimes type
the Kbuild item different.
Let's standardise every occurrence using the same syntax.
The changes were generated by this small shell script:
for i in `find linux -type f`; do sed s,CUSTOMIZE,CUSTOMISE,g $i >/tmp/a && mv /tmp/a $i; done

paging request at ffffffff
I'm using a "Hauppauge WinTV-NOVA-T DVB card" of PCI id "13c2:1005" with
kernel 2.6.27.9.
I've recently experienced the following fairly consistent kernel oops on
startup in grundig_29504_401_tuner_set_params from budget.c. As you
might expect, following this failure, the card doesn't work.
I'm not a kernel developer, nevertheless I seem to have managed to track
this down to a non-existent initialisation of
budget->dvb_frontend->tuner_priv.
The attached patch fixes the problem for me (and I've managed to tune
the card successfully as a result), but I don't know of anyone else
using the driver so I can't test it on other people.
Please let me know if this works for you or if I've done something
terribly wrong ;-(

Since internal to v4l2 the ioctl prototype is the same regardless of it
being called through .ioctl or .unlocked_ioctl, we need to convert it all
to the long return type of unlocked_ioctl.

thus bringing it to our attention.

Introduce a struct v4l2_file_operations for v4l2 drivers.
Remove the unnecessary inode argument.
Move compat32 handling (and llseek) into the v4l2-dev core: this is now
handled in the v4l2 core and no longer in the drivers themselves.
Note that this changeset reverts an earlier patch that changed the return
type of__video_ioctl2 from int to long. This change will be reinstated
later in a much improved version.
